ROUTE.CONF(5) File Formats Manual ROUTE.CONF(5)

NAME

route.confstatic routes config file

DESCRIPTION

The route.conf file is read by the staticroute rc.d script during system start-up and shutdown, and is intended for adding and removing static routes.

FILE FORMAT

Lines starting with a hash (‘#') are comments and ignored. Lines starting with a plus sign (‘+') are run during start-up, while lines starting with a minus sign (‘-') are run during system shutdown. If a line starts with a ‘!', the rest of the line will get evaluated as a shell script fragment. All other lines are passed to route(8). During start-up, they are passed behind a “route add -” command and during shutdown behind a “route delete -” command.

FILES

/etc/route.conf
The route.conf file resides in /etc.
/etc/rc.d/staticroute
rc.d(8) script that parses route.conf.

EXAMPLES

In this example, the interface for the desired routing changes is set, the IP address on that interface is determined, and a route is added during startup, or deleted during system shutdown.

# Set interface and determine current IP address for added route. 
!ifname=bnx0 
!ipaddr=$(/sbin/ifconfig ${ifname} | awk '$1 == "inet" {print $2}') 
net 10.10.1 -interface ${ipaddr}

In this example, IP forwarding is turned on during start-up, and a static route added for 192.168.2.0. During system shutdown, the route is removed and IP forwarding turned off.

# Turn on/off IP forwarding. 
+sysctl -w net.inet.ip.forwarding=1 
-sysctl -w net.inet.ip.forwarding=0 
net 192.168.2.0 -netmask 255.255.255.0 192.168.150.2
